I went to Glasgow last week and I was worried that I would have nothing to do, because I don’t enjoy sightseeing very much. My mom made sure that the one thing that I really wanted to do would happen. I wanted to go to the Falkirk Wheel. The Falkirk Wheel is what connects two canals. The reason they need a connection is because one is eighty-five feet above the other. Without the Falkirk Wheel it would just be a waterfall. The Falkirk Wheel is basically just a bridge that goes nowhere. Two of the poles that support the bridge going of the cliff, connect at the bottom. The water from the canal below gets trapped in the connection. The connection is called a gondola. Then those two poles rotate, so the water from the bottom gets to the top. But at the same time, the water from the top goes to the bottom on the other side of the pole. But the part that people can go on is the boats. The gondolas are big enough to hold a boat with a lot of people. Because of Archimedes’ theory that a mass in water weighs as much as the water it displaces, both gondolas weigh the same at all times.
